The task of the armed forces is to safeguard national security and defend the country against attacks.

Research at NUPI is engaged in developing ideas, theories and procedures for the armed forces, in Norway and abroad. We focus on combining the overarching issues of security policy with the practical and technical military challenges involved. NUPI works closely with military practitioners and academic scholars, internationally as well as domestically, seeking to bridge the gap between analyses on the political level and on the ground.
Some topics of NUPI research in the sphere of defence:
•    maritime security
•    cyber-security
•    new technology
•    civilian–military relations
•    irregular warfare.
